Prussian T 7
The Prussian T 7 was a group of goods tank locomotives of the Prussian State Railways with an 0-6-0T wheel arrangement. It was not a class in the modern sense of identical locomotives.
In terms of construction, they go back to the mountain locomotives that had been procured by the Rhenish Railway Company (Rheinische Eisenbahn, RE) which had also changed little from the Upper Silesian Railway, (Oberschlesische Eisenbahn, OSE), the K.Dir. Saarbrücken and the Lower Silesian-Märkische Railway (Niederschlesisch-Märkische Eisenbahn, NME). A second, slightly revised series, delivered to the latter company in 1881, proved itself so well that its design was adopted as Diagram (Musterblatt) III-4c in the Prussian Standards. The standardization of the classifications, begun in 1905, summarized all locomotives of this type that were still in existence at that time – both the "standard" and the "pre-standard" – at the Prussian Railways in the group T 7. So 65 locomotives (e.g. 33 of the OSE, 14 of the K.Dir. Saarbrücken, but also 1 of the Thüringische Eisenbahn-Gesellschaft), which were built before the standard were issued, were included in this group. Even after the group was formed, a total of 28 came into the Prussian administration, all of which had construction designs that differed from the diagram sheet. With the 374 copies procured according to the diagram sheet, there is consequently the number of 467 machines that were grouped as T 7 by the Prussian State Railway.
The locomotives were mainly used in heavy shunting. Therefore, they were mainly stationed in the industrial areas. After the First World War, among other things, three locomotives were sold to the South German Railway Company (Süddeutsche Eisenbahn-Gesellschaft, SEG), where they were designated as SEG 370–372.
After the First World War, 27 locomotives were ceded to Poland. The Polish State Railways (PKP) classified them as TKh2, none of which were in service during the invasion of Poland.
Some of the state railway locomotives were later taken over by Deutsche Reichsbahn; while in 1923, 137 T7s were still considered as 89 7801 to 89 7937 in the renumbering plan for regional railway locomotives of DRG; in 1925 only 68 examples were classified as the Class 89.78 series in their numbering plan. By 1931, however, all of these machines had been taken out of service.
As a result of the turmoil of the war and post-war period, some machines are said to have reached Belgium and Latvia.
Another machine came in 1930 from the nationalized Bremen Harbour Railway (Hafenbahn Bremen) as 89 7869 to the Deutsche Reichsbahn, was sold to the Kreis Oldenburger Eisenbahn AG and with this came back to the Reichsbahn in 1941. After the Second World War, only a few examples existed on private and works railways.
After the SEG route of the Arnstadt-Ichtershausen Railway was taken over by the Deutsche Reichsbahn in 1949, the SEG 372 was given the number 89 6401. It was in service there until 1956 and was sold to the Erfurt industrial railway, where it remained until it was retired in 1967.
